SAT modulo symmetries for graph generation and enumeration

M Kirchweger, S Szeider - ACM Transactions on Computational Logic, 2024 - dl.acm.org
We propose a novel SAT-based approach to graph generation. Our approach utilizes the
interaction between a CDCL SAT solver and a special symmetry propagator where the SAT …

Simplest bipartite perfect quantum strategies

A Cabello - Physical Review Letters, 2025 - APS
A bipartite perfect quantum strategy (BPQS) allows two players who cannot communicate
with each other to always win a nonlocal game. BPQSs are rare but fundamental in light of …

Optimal conversion of Kochen-Specker sets into bipartite perfect quantum strategies

S Trandafir, A Cabello - Physical Review A, 2025 - APS
Bipartite perfect quantum strategies (BPQSs) allow two players isolated from each other to
win every trial of a nonlocal game. BPQSs have crucial roles in recent developments in …

Satisfiability modulo user propagators

A SAT Solver's Opinion on the Erdős-Faber-Lovász Conjecture

M Kirchweger, T Peitl, S Szeider - 26th International Conference …, 2023 - drops.dagstuhl.de
Abstract In 1972, Paul Erdős, Vance Faber, and Lászlo Lovász asked whether every linear
hypergraph with n vertices can be edge-colored with n colors, a statement that has come to …

Computing Small Rainbow Cycle Numbers with SAT Modulo Symmetries

Envy-freeness up to any good (EFX) is a key concept in Computational Social Choice for the
fair division of indivisible goods, where no agent envies another's allocation after removing …

Small unsatisfiable -CNFs with bounded literal occurrence

T Zhang, T Peitl, S Szeider - arxiv preprint arxiv:2405.16149, 2024 - arxiv.org
We obtain the smallest unsatisfiable formulas in subclasses of $ k $-CNF (exactly $ k $
distinct literals per clause) with bounded variable or literal occurrences. Smaller …

On the Quantum Chromatic Numbers of Small Graphs
